Introduction to pharmaceutical calculations/

Abstract

Introduction to Pharmaceutical Calculations introduces the mathematical principles and practical skills required for accurate pharmaceutical calculations in pharmacy practice. The book explains fundamental arithmetic concepts, measurement systems, unit conversions, ratios, proportions, percentages, and calculations involving concentrations and strengths of pharmaceutical preparations. It covers the preparation and dilution of solutions, calculations involving doses and dosage regimens, body-weight and body-surface-area-based dosing, molecular weights, moles, millimoles, and intravenous infusion rates. It also addresses pharmaceutical formulation calculations, quantities of ingredients, displacement values, and other mathematical applications relevant to the preparation, dispensing, and administration of medicines. Through worked examples and practice exercises, the text helps pharmacy students develop numerical competence, accuracy, and confidence in solving pharmaceutical problems. It serves as a useful educational and reference resource for pharmacy students, pharmacy technicians, and healthcare professionals involved in medication preparation, dispensing, and safe medicine use.
